Kings of War: Forces of the Abyss - Abyssal Berserkers Regiment

The Abyssal Berserkers are Abyssal Champions that spend so long fighting relentless wars against their kin that their bodies twist and warp as surely as their vicious minds.
 
They grow into towering beasts known as Berserkers, for whom the hunting of prey and the slaughtering of foes is meat and drink. Berserkers are marked by their regenerative powers, allowing them to heal the most grievous wounds, so that they might better continue the eternal battle.
